etcdctl: use user specified timeout value for entire command execution

etcdctl should be capable to use a user specified timeout value for
total command execution, not only per request timeout. This commit
adds a new option --total-timeout to the command. The value passed via
this option is used as a timeout value of entire command execution.

Fixes coreos#3517
release-2.3
